Current balance
Existing retirement accounts, taxable investments, or rollover funds to project forward.
Monthly contribution
Enter directly, or use the 15% helper to convert household income into a monthly investing target.
Return assumption
12% is Ramsey's optimistic case. The 6–10% scenarios stress-test the plan against realistic markets.
Monthly compounding, deposit-aware.
The monthly rate is the annual return divided by 12. Each month the balance grows, and the contribution lands at the start or end depending on your setting.
The annual breakdown isolates contributions from compounding so you can see exactly how much wealth came from money invested versus growth on top.
Use 12% sparingly
Treat it as the upper bound for an optimistic, long-horizon illustration — not a guarantee.
Plan around 8–10%
Sequence risk, fees, and behavior gaps make conservative rates more useful for the actual plan.
Watch real value
The inflation-adjusted balance is what future purchasing power actually looks like.
Educational planning tool. Not affiliated with Dave Ramsey or Ramsey Solutions. Not investment, tax, or retirement advice. Market returns are uncertain; past performance does not guarantee future results.
What does the Dave Ramsey investment calculator do?→
It estimates how a current investment balance and monthly contributions could grow over time using a selected annual return. The default 12% scenario reflects the optimistic return assumption often associated with Dave Ramsey planning examples, and the tool also helps estimate a monthly contribution equal to 15% of household income.
How is the 12% investment scenario calculated?→
The calculator divides the annual return by 12, applies that monthly rate to the balance, and adds the monthly contribution either at the start or end of each month. It repeats that process for the full investment period and totals contributions separately from growth.
Is a 12% return guaranteed?→
No. A 12% annual return is an assumption, not a guarantee. Actual market returns vary by period, fees, taxes, fund selection, and investor behavior. Use the lower scenarios to test whether your plan still works with more conservative returns.
Is this a Dave Ramsey retirement calculator?→
It is focused on the investment-growth part of retirement planning: current balance, monthly contributions, return assumptions, inflation, and projected future value. It does not estimate Social Security, taxes in retirement, pension income, healthcare costs, or a full retirement spending plan.
How do I use the 15% investing guideline?→
Enter your household income and use the 15% button to convert that annual target into a monthly contribution. For example, 15% of $80,000 is $12,000 per year, or $1,000 per month before any employer match or tax treatment.
Why does the calculator show inflation-adjusted value?→
Inflation-adjusted value estimates the purchasing power of the future balance in today's dollars. A large nominal balance can support less real spending if inflation is high over a long time period.
